EXHAUEST-HEATED VULCANIZER.

Specification of Letters Patent.

Application filed October 28, 1914. Serial No. 869,088.

.an internal combustion engine.

The primary object of my invention is the provision of a vulcanizing plate which is arranged to be heated by the exhaust pipe of an internal combustion engine, the plate being preferably, though not necessarily detachably mounted upon the exhaust pipe so that it may be readily putin placeor' removed therefrom.

A further object of the invention is to provide a vulcanizing plate which will be kept continually heated while a car isrun-i ning and which is thus in condition forimmediate use if a tire puncture occurs.

A further object of the invention is the provision in connection with a vulcanizing plate adapted to be mounted upon an exhaust pipe, of a thermometer disposed in the vulcanizing plate where it may be readily read. i

Other objects will appear in the course of the following description.

My invention is illustrated in the accomp y g, than a Figure 1 is a side elevation of a portion of theexhaust pipe of an engine and of my improved vulcanizer plate mounted thereon, the plate being in side elevation, one corner of the plate being broken away; Fig. 2 is an end view of the vulcanizing plate, the exhaust pipe being in section, and one corner of the plate being broken away.

Corresponding and like parts are referred to in ,the following description and designated in all parts of the accompanying drawing by like reference numerals.

Referring to these figures, 1 designates.

the exhaust pipe .of an automobile engine, and 2 a vulcanizing plate mounted thereon. This plate isformed of a relatively thick rectangular body of iron or other suitable metal, cut away upon its under side as at 3 so as to fit over the exhaust pipe 1, and

have its under face incontact with the curved outer face of the exhaust pipe so that there is intimate contact between the may be quickly and fully transmitted to the plate. The upper face 4 of the plate is of course flat. The plate is held in engagement with the exhaust pipe by any suitable means, but I have shown for this purpose the set screws 53 which extend through one s de of the plate and into the cut away portion thereof so as to bind against thepipe.

In order that the. temperature of the Vulcanizing plate may be noted so that accurate vulcanizing may be performed, I-provide in. connection with the plate .and preferably embedded therein, the thermometer 6. This thermometer is inserted in a bore .7 which extends longitudinally of the vulcanzing plate adjacent one of its upper corners, and this bore is closedafter it is mounted in place by means of a plug 8, of-

nor of the plate is cut away as at',9, it being of course understood that thethermometer is longer than this cut away portion 9. It will be noted that as the corner of the plate is cut away, the thermometer may be read either from the top of the plate or from one side thereof.

to this end I have shown a block 10, preferably of wood, which is intended to be dis- Any suitable means may be used in con posed upon the upper face of the plate, and

I liave'also shown a clamp 11, one end. of which engages beneath the exhaust pipe or beneath any suitable abutting member, the

other end of which extends over the topof the vulcanizing plate and has extending 1 therethrough the screw 12, the lower end', of which is adapted to bear against the upper face-of the wood block 10.

It will be"understood' that the tube in which a puncture has occurred and which it is desired to vulcanize is to be disposed with the punctured part between the wood block and the vulcanizing plate, a suitable patch having been applied to the puncture, and the wood block is then forceddown against the plate-by meansof the screw 12. The

, therefrom after use.

Wood block and the screw clamp are intended of course to be carried in the tool box of the automobile, but the vulcanizing plate is intended to be attached at all times to the exhaust pipe and is not removed Thus the vulcanizer is ready for use if any punctures occur on the road.

The provision of a thermometer in conjunction with the vulcanizing plate is of particular value, as thereby accurate vulcanizing may be performed, which is not the case where vulcanizers are heated by gasolene lamps and with no provision for determining the degree of heat to which the vulcanizing plate has been raised.

It will be seen that my improved Vulcanizing plate is extremely simple, may ":be readily applied and detached, may be used practically on all forms of motor vehicles,

' and 1s extremely handy in use.

While I have referred to the pipe 1 as the exhaust pipe of an engine, it will be understoodthat Where automobiles are driven by steam power the plate might be applied equally well to a steam pipe.

It is also to be understood that while I preferably mount the plate detachably upon the exhaust pipe, yet the plate might be cast with the exhaust pipe, and still be within the scope of my invention.

Having described my invention, what I claim is:

1. The combination with a pipe carrying heated vapors, of a solid vulcanizing plate detachably mounted upon the pipe and having athickness greater than the diameter of the pipe and a recess having a depth approximately equal to the diameter of the pipe whereby to provide oppositely disposed depending portions engaging on each side of the pipe, and means passing through one of said depending portions for engaging the pipe and clamping the vulcanizing upon the pipe.

plate 2. A vulcanizing attachment comprising a plate cut away upon its under face to fit over and partially embrace the exhaust pipe of an internal'oombustion engine, said plate having a flat upper face, a clamping plate confronting the flat upper face of the vulcanizing plate, and a clamp comprising a body having one terminal adapted to engage with the under face of the exhaust pipe and the other terminal extending over the upper face of the clamping plate, and a clamping screw passing through the last-named terminal and engaging with the clamping plate.

3. A vulcanizing attachment comprising a plate cut away upon its under face to fit over and contact with the exhaust pipe of an internal combustion engine, and provided with oppositely disposed depending portions engaging on each side of said exhaust pipe, a screw passing through one of these depending portions and adapted to engage the exhaust pipe to detachably hold the vulcanizing plate in place thereon, and a clamping member approximately U-shaped in form adapted to have one terminal engage beneath the exhaust pipe and the other terminal extend. over the vulcanizing plate, and a clamp screw passing through this lastnamed tern'iinal.

4. A vulcanizing plate having a thickness greater than the diameter of an automobile engine exhaust pipe and being recessed at its funder side to fit over the said exhaust pipe and contact therewith, said recess having a depth approximately equal to the diameterof the exhaust pipe, said vulcanizing plate having a longitudinal bore extending from one end. of the plate adjacent an upper corner thereof, a corner of the plate being cut away to intersect this bore, means for detachably engaging said plate with the exhadst pipe of the engine, and a thermometer mounted within the bore and entirely housed thereby, the thermometer being read through the cut away corner of the plate.

5. A vuloanizing plate for detachable connection to the exhaust pipe of an automobile engine, said plate having a thickness greater than the diameter of the exhaust pipe and being recessed on its under side to fit over the exhaust pipe and contact therewith, said recess having a depth approximately equal to the diameter of the exhaust pipe, and means passing through the side of the vulcanizing plate and adapted to engage the exhaustpipe to hold the vulcanizing plate in place thereon.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
